Do rolled oats really have the same nutritional values as quick oats?

Recently switched to rolled oats (old fashioned) and i find that i am way more full compared to when i was eating quick oats but the packaging has identical nutritional info.

I ate the same amount of oats that i would normally eat but i was so full i had mild heartburn. I also found that I had to drink more water and became more vascular which might indicate that im getting the 'carb up' effect.

As far as I know, NO OATS are eaten with the outer hull. It is removed for all of the three types being discussed in this thread.

The difference between old fashioned oats and instant is just that the oats will be cooked and dried at the end of the processing when you make them instant. This allows you to not even have to cook instant oats - just add hot water and eat.

Of course this is assuming that the "instant" oats don't have sugar and other stuff added as many do when they are packaged in packets, which obviously changes things.
